Sheet refers to the single pole sheet made in the die cutting process is stacked into a cell. Generally speaking, winding is used for square and cylindrical batteries, and lamination is used for square and soft pack batteries. According to GGII calculation data, in the lithium equipment, the value of the middle equipment accounted for about 35%, of which, the winding/lamination …
Due to its adhesive nature, roll-to-roll processing for lithium is difficult to employ. Instead, a lamination process via extrusion can be implemented to secure the anode material …
First time, the lamination technology was used in the assembly process during the lithium ion battery production in 1996 [22]. Later specific roller lamination technique was reported as a binding technique to prevent the air bubbles and wrinkles within the laminated material for preparing the supercapacitor electrode on a current collector [25].

It should be noted that the cylindrical batteries use winding process, while soft-packed batteries adopt laminating process. Second, the cell needs to be tested under high voltage (200–500 V) to detect whether there is a high-voltage short circuit, and the cell is vacuumized, and then the wound cell is put into the shell.
The lamination & stacking process is a lithium polymer battery manufacturing process in which a positive electrode, a negative electrode is cut into small pieces and a separator is laminated to form a small cell, and a single cell is stacked in parallel to form a large cell. However, there are different ways to stacking process.
